Q3:
acanthodii:have bony bone stucture including cartilage bones
actinopterygii:they fin rays meaning their fins being webs of
skin supported by bony or horny spines.
amphibia: animals that either metamorphose from a juvenile
water-breathing form, to an adult air-breathing form
ascidiacea:sac-like marine intvertebrate filter feeders
aves:it has feathers wings and reproduce by eggs
Chondrichthyes: jawed fish with paired fins, paired nares,
scales, two-chambered hearts, and skeletons made of cartilage
rather than bone.
hyperoatia:are jawless fish which feed on other fish's tissue
leptocardii:have fish like structure but does not hae paired fins and a heart
mammalia:they have fur and reproduce by living
myxini:they are basically eels with no true fins
placodemi:are armoured prehistoric fish head and thorax were
covered with articulated armoured plates and the rest of the body
was naked or scaled
reptilia:cold-blooded with scales or scutes amniotic eggs
(amniotic is a membrane which surronds the embryo)
sarcopterygii:are lobed finned fish
sorberacea:they resemble sea squirts but eat interverbrates
thaliacea:they barrel shaped bodies pumping water propelling
them through the water

1.
Cnidarians: jellyfish
Molluscs:snails
Arthropods:crabs
worms:tape worms
Echinoderms:starfish

unit: matter

soilds

soilds mocules are very close to each other and the feeling when you touch a solid is either rough or different roughness

liquids

liquids the mocules are not that close together like a solid but yet it is not too far apart like a gas so it can take the shape of any container

gases

gases their molcules are very far apart so its mass can change unlike other states of matter

can you trust your senses


1. Where does the most bending of the light occur in the eye?
external image Eye-1.jpg
it happens in the lens mostly as it is a bioconvex stucture and that it bends most of the light into the retina
2. Describe how the lens works
the lens work by refeacting the light rays so that they change direction. this is as it is a convex lenses and that it is able to focus the light rays into a focal point this is as the musclces relax and flatten the lens and when they contract it rounds the lens and sees things closers
3. Why do we squint when exposed to bright light?
the musclces relax and flatten the lens and when they contract it rounds the lens and sees things closers
4. Which parts of the eye are involved in focusing?
the lens and the cornea. as the cornea focuses the light into the pupil and the lens focuses it into the retina
5. Discuss the implications of losing one eye?
you would not be able to tell the distance an object to another object and you would not be able to see things in 3D but you will only be able to see things in 2D


  • Discuss: Visual impairment

visual impairment is when you have a eye disorder with either a disease or geneticaly or an injury that happens to your eye which affects your vision or your ryr in some way
  • Do you know anyone who wears glasses or contacts? Why? How do glass or contacts help?

yes i wear glasses. because i am short-sighted. the glasses help because the light is focused is too short and does not reach the macula and thus the things i see from afar is rather blury but when i wear glasses this helps to let the light reach the macula and thus this allows me to see better
  • Are there other solutions for people with visual impairments?

there is one other solution which is to go for laser surgery which changes the shape of your cornea which helps your eyesight
Use the resource from the last section to find out about visual impairments
-describe two visual imapirments
one viual impairments is macual degeneration which is when the photoreceptors wear out and in your vision you start to have a spot in which you are unable to see and the second visual impairment is cataracts which clouds the lens of your eyes and this fogs up your vision
-describe some possible solutions.
for macual degeneration so far there is no treatment for it but you can prolong or try to prevent it from happening by eating healthly for the second visual impairment so far there is only one treatment which is to transplant a new lens into your eye.
-Find a picture or video clip and use this to support your ideas on your student page.

Student task four

Research an animal that has unsual senses.
Include a picture

external image snakes-portrait-photography.jpg

Describe which sense are developed in a special way

PIT-VIPERS HAVE A HEAT SENSITIVE ORGAN(MEMBRANE) BETWEEN THE EYES AND THE NOSE ABOUT HALF A CENTIMETER DEEP AND IT CONTAINS 7000 NERVE ENDINGS WHICH ALLOWS THE ANIMAL TO SENSE ANY NEARBY ANIMAL WHICH IS ABOUT 40 TO 10CM AWAY FROM THE PIT-VIPERS
How do they work - how does the animal use them?
THEY STAY IN A PIT AND WHEN THE ANIMAL COMES INTO RANGE IT CAN SENSE IT
Are any of the animal's senses UNDERDEVELOPED?
THEY DO NOT HAVE ANY EARS
Why do you think this is?
BECAUSE IT IS NOT USEFUL WHEN YOU ARE IN A PIT WHERE YOU ARE IN A HOLE
